 I think, once Montague said that the Cabinets connect Hogwarts
to Borgin & Burke, SOMEBODY thought this information was too important to
get out. So Montague's memory was erased, his body was moved, and he was
given befuddlement potion until the end of term so that he couldn't share
the story with anyone else. 

Magpie:
But he *did* share the information with someone else. He shared it with all
of Slytherin.That's where Draco heard it, as he explained, and realized
what it meant. Montague's memory wasn't erased, he was, as far as we know
now, just befuddled by being trapped in limbo with no way to get out or
make anyone hear him--until he managed to Apparate into the toilet. Which
completely goes against what we've been told about Apparition it's true,
and also goes against the fact that the Vanishing Cabinets are broken. It
could be a special circumstance, with the rule-breaking Apparition being
part of the ill-effects.

But so far it seems important that Montague doesn't have missing gaps in
his memory--we hear his whole story as told to the Slytherins in  HBP, some
of the details of which are demonstrated via that Cabinet Plot. 

As to why the Twins weren't punished, I don't think they could have been.
Montague was still befuddled when they left school, I think, so there was
no one to punish once Montague came around. Before that no one but the Trio
knew what happened to him and they weren't talking.

If we see any bright blue Potions I will definitely connect it to whatever
Montague was taking, but the fact that it was bright blue so far doesn't
seem to be any evidence that it was Confunding him. After all, eventually
he did get better and share his story. And if somebody memory charmed him,
particularly if Snape memory charmed him, since Snape is a competent adult,
he could just be memory charmed, couldn't he? And if he was being given
Potions to keep him Confunded, why was he able to tell the whole "great
story" to the Slytherins?
